In this article, we present part of the results from a wide-ranging research study addressing "Orquestra Geração" (OG), a "Sistema"-like project set up in Portugal in 2007. "Orquestra Geração" strives to bring about, through collective musical practices, the social inclusion and social mobility of children and teenagers experiencing educational and social vulnerability. The data collected include semi-structured interviews with three OG mentors, one of whom currently serves as the OG director, the OG sub-director, former national coordinators, the current national coordinator, and school coordinators, as well as observations of music classes, orchestra rehearsals and intensive summer internships. We briefly describe the project before detailing the organization's identity and the profile of its music teachers in a narrative highlighted by the actors' own words. Finally, we analyse the OG through the lenses of two different and yet complementary conceptual frameworks: Mintzberg's organizational typology, and Cultural-Historical Activity Theory, as expanded and applied by Engeström. Findings suggest an underlying tension between adopting "El Sistema"'s methodology, as implemented in Venezuela, and adapting this to the Portuguese context. Moreover, a concentration of power in a few key figures may possibly prevent "Orquestra Geração" from prospering within a framework where its identity stands out as an autonomous project from "El Sistema."
